I don't think this is related to source-highlight in my case, because
I have only the static libsource-highlight.a library installed.  (I
didn't install the shared library version precisely because it depends
on libstdc++ DLL.)

I think Pedro explained why I suddenly have the dependency on libstc++
DLL where I didn't with previous GDB versions: we no longer inherit
-static-libstdc++ switch from GCC.  It now has to be requested
explicitly, via --with-static-standard-libraries.
